Your Privacy Matters
Web SuperKit — a sidebar for developers & designers — is built with a privacy-first mindset. Every single tool runs entirely inside your browser— no data is ever sent to external servers, no behaviour is tracked, and no personal information is collected.
Last updated: June 09, 2026
Designed to respect you
100% Local Processing
Every tool runs entirely inside your browser — nothing leaves your device.
Zero Data Collection
We do not collect, store, or transmit any personal data whatsoever.
Lightweight (<1 MB)
Tiny footprint, zero third-party SDKs, no analytics bundles.
User-Controlled Features
Every tool activates only when you explicitly trigger it.
How Web SuperKit handles your data
All processing happens in your browser
Every tool — from CSS inspection to color picking, from element analysis to screenshot generation — runs entirely within your local browser environment. There is no cloud backend, no API calls to our servers, and no remote processing of any kind.
No personal data is collected, stored, or transmitted
We do not collect your name, email, IP address, browser fingerprint, or any identifiable information. Web SuperKit has no analytics pipeline, no crash-reporting service, and no telemetry of any kind.
No third-party analytics or tracking scripts
The extension bundle contains zero third-party tracking SDKs — no Google Analytics, no Mixpanel, no Segment, no Hotjar. Our install size stays under 1 MB specifically because we refuse to bundle unnecessary code.
No remote servers involved
Web SuperKit does not communicate with any external server during normal operation. If a specific tool makes a network request, it happens only when you explicitly trigger that tool — from your browser — and is limited to the data required to complete that action.
What data is stored — and where
Web SuperKit stores a small amount of data to remember your preferences between sessions. Here is exactly what is saved:
This data is stored exclusively on your device and is never synced, transmitted, or accessible by us.
Every permission — explained
We request only what is strictly necessary. Here is what each permission does and exactly why it is needed.
sidePanelDisplay the sidebar dock on any page
Web SuperKit lives in a side panel that opens on any website. This permission lets the extension render its full UI — tool dock, settings, and active tool views — directly in the browser's side panel area on the page you choose.
activeTabAccess the current tab temporarily
Grants temporary, on-demand access to the active tab only when you interact with a tool. The extension has no background access to any tab you haven't explicitly opened a tool on.
scriptingInject tool scripts on demand
Enables powerful in-page tools such as the CSS inspector, color picker, element analyzer, and visual editor. Scripts are injected only when you activate a specific tool — never silently on page load.
tabsRead the active tab's URL and title
Used exclusively to display the current page's URL, title, and favicon in the sidebar header and toolbar. This data never leaves your device and is used only for in-extension UI — no browsing history is recorded or transmitted.
webNavigationDetect page navigation for toolbar updates
When you navigate to a new page, this permission signals the extension to refresh its toolbar state and tool availability. No browsing history is recorded, stored, or transmitted — the data is used ephemerally and discarded immediately.
storageSave your preferences locally
Used to persist your pinned tools, UI settings, custom shortcuts, and tool-specific preferences using the browser's built-in storage API. This data is stored exclusively on your device and never leaves it.
unlimitedStorageStore larger tool data without limits
Some tools — such as media extraction, asset collections, and colour palette exports — may need to store more than the default 5 MB storage quota. This permission removes that ceiling so large datasets can be saved reliably, entirely on your device.
What the extension reads
- DOM structure needed for the tool you activate (e.g. the element you click/hover).
- Computed CSS styles, box model metrics, and attributes for inspection tools.
- Visible text/colors/fonts only when required by a specific tool.
What the extension injects / modifies
- Injects a UI dock/panel into a dedicated container and renders it inside a Shadow DOM to avoid CSS conflicts.
- Attaches event listeners for tool interactions (click, hover, key shortcuts) while the tool is open.
- May temporarily add overlays/highlights (e.g. outlines, measurement guides) and removes them when you close the tool.
These operations happen only on the page where you activate Web SuperKit, and the data stays in your browser.
What Web SuperKit does not do
- Collect any personal data
- Track your browsing history or behaviour
- Send data to external servers
- Use third-party analytics or tracking (e.g. Google Analytics)
- Show advertisements
- Sell or share data with third parties
- Run scripts in the background without your interaction
- Request unnecessary permissions
Security & transparency
Minimal permission footprint
We reviewed every permission request against the extension's features. If a permission is listed, there is a concrete UI or tool that relies on it. The sidePanel and activeTab permissions allow the extension to operate on the page you choose — not to monitor your browsing.
Activated only on your action
Content scripts and tool logic run only when you explicitly open a tool or use a shortcut. There is no persistent background monitoring of any page.
Designed for user control
You can disable any tool, remove shortcuts, and reset all settings at any time from the extension's settings panel. Uninstalling the extension immediately removes all locally stored preferences.
No hidden code paths
The extension follows Chrome's Manifest V3 standard, which enforces strict limits on background behaviour and remote code execution. There are no remotely loaded scripts or dynamic code evaluation.
Changes to this policy
If we make meaningful changes to this privacy policy — for example, if a future version of the extension introduces new data handling behaviour — we will update this page and communicate the change clearly through the Chrome Web Store update notes. We will never silently change how data is handled. The “Last updated” date at the top of this page reflects the most recent revision.
